Isolation and characterization of a motile hydrogenotrophic methanogen from rice paddy field soil in Japan.
A hydrogenotrophic motile methanogen was isolated from flooded Japanese paddy field soil. Anaerobic incubation of the paddy soil on H(2)-CO(2) at 20 degrees C led to the enrichment of symmetrically curved motile autofluorescent rods. The methanogenic strain TM20-1 isolated from the culture was halotolerant and utilized H(2)-CO(2), 2-propanol-CO(2), or formate as a sole methanogenic substrate. B...
متن کاملFormation of Microbial Mats and Salt in Radioactive Paddy Soils in Fukushima, Japan
Coastal areas in Minami-soma City, Fukushima, Japan, were seriously damaged by radioactive contamination from the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident that caused multiple pollution by tsunami and radionuclide exposure, after the Great East Japan Earthquake, on 11 March 2011. Some areas will remain no-go zones because radiation levels remain high. In Minami-soma, only 26 perce...

15 صفحه اولMineralization of metsulfuron-methyl in Chinese paddy soils.
A laboratory study was conducted to investigate the mineralization of metsulfuron-methyl (MSM) in paddy soils in response to soil moisture, temperature and soil properties. The results indicated that MSM mineralization was relatively limited in the paddy soils when soil temperature was low. Only 2.2-6.0% of the applied (14)C mineralized after 84d of incubation at 15 degrees C. The mineralizatio...
متن کاملResidues of 14C-metsulfuron-methyl in Chinese paddy soils.
BACKGROUND Metsulfuron-methyl is widely used for controlling many annual grasses and broadleaf weeds in cereal crops. Nonetheless, increasing evidence has demonstrated that even extremely low levels of metsulfuron-methyl residues in soil can be toxic to subsequent crops or non-target organisms. The behavior of herbicides in soils is mostly related to their residual forms. The intent of the pres...
